WILLIAM F. JACOBS, 0F OTTAWA, ILLINOIS, ASSIGNOR TO J. E. PORTER COMPANY, A CORPORATION OF ILLINOIS.

CROSS-DRAFT HAY-CARRIER.

Specification of Letters Patent.

Patented Apr. 4:, 1911.

To aZZ whom 'it may concern:

Be it known that I, IVILLIAM F. JACOBS, a citizen of the United States, and a resident of Ottawa, in the count-y of La Salle and State of Illinois, have invented certain new and useful Improvements in Cross-Draft Hay-Carriers; and I do hereby declare that the following is a full, clear, and exact descrip-tion thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specication.

This invention relates to improvements in hay carriers, and more particularly to the cross draft carrier by means of which the .hay slinois suspended from the overhead track antd is raised or lowered in loading or unloading, and is transported from one place to another.

The invention relates particularly to an improved locking mechanism by means of which the draft rope may be locked or unlocked in any position of the load.

The invention consists in the combination of parts hereinafter described and more particularly pointed out in the claims.

In the drawings z-Figure l is a perspective view of my improved cross draft carrier in position on its track. Fig. 2 is a top plan view of the same. Fig. 3 is a side elevation of the carrier. Fig. I is a vertical section through Fig. 3 on the line 4 4 thereo-f. Fig. 5 is a transverse section through Fig. 3 on the line 55 thereof. Fig. 6 is a vertical section through Fig. 2 on the line 6 6 thereof. Fig. 7 is a vertical section through Fig. 2 on the line 7-7 thereof.

In the drawings, A indicates the overhead track and B, the cross draft carrier as a whole. The carrier comprises a frame C consisting of V-shaped open side frames C1, C1, braced apart and secured rigidly in parallel relation to each other and provided at their upper ends with hanger extensions c, one at each end of each side frame, to which are pivotally attached truck members A1 provided with wheels a which engage on opposite sides of the overhead track. As will be seen from the drawings, there are eight of said wheels a, four arranged on each side of the track in order to suit-ably support the frame C in suspended rolling relation below the track.

D indicates an auxiliary frame which is arranged transversely of the main frame C and which extends through vertical slots C2 formed in the vertical side frames C1. Said frame D comprises U-shaped side members D1, D1, between which are suspended two sheaves or pulleys E and F, and to the upper ends of t-he legs of which is secured a jaw member (Z. Said jaw extends the length of the auxiliary frame D and is curved on its bottom side transversely of its length witlli the concave side down, as indicated at c 1.

(Z1, (Z1 indicate upright guide plates projecting from said jaw which engage within slots (Z1, Z2 formed through the top webs of the main frame side plates C1, C1. A fixed jaw E1 is located below the jaw Z and is secured tothe main frame C. Said jaw is parallel to the first named jaw and it is curved transverse of its length, but with its concave side up, as indicated at cx. Suitable openings a-re formed at the side of the fixed jaw member to permit the legs of the U-shaped plate to pass up beyond said fixed jaw member.

F1 F1 indicate depending lugs which pass downward through suitable slots f f formed at the sides of the fixed jaw E1 in position to be engaged by the short arms G1 of a pair of levers G, Gr pivoted to the main frame C by' means of depending ears g g, depending from the fixed jaw E1, one on each side of the supplemental frame D. The long arms G2 G2 of said levers project laterally beyond the main frame C and carry between their ends a pulley J. Said pulley J is located a sufficient distance beyond the frame C so as not to interfere with the sheave or pulley E, as it is moved up or down by the levers Gr G.

L L1 indicate a pair of parallel pulley blocks which are 'provided with hooks Z Z1 to which the ends of the slings indicated at M M1 are attached. Said pulley blocks have pulleys Z2 Z3 and to one of said blocks L is fixed one end of the draft rope K, as indicated at Z4.

The draft rope K (see Figs. 1 and 7) passes over the pulley J, thence between the movable jaws Z and the fixed jaw E1, thence over the sheave F, then about the pulley Z1, thence about the pulley Z1, then up about the sheave E, and back to the block L.

From the above description it is apparent that, with the weight of the hay carried by 'for the slings M M1, pulling down on t-he sheaves E, F and thence on the auxiliary frame D and with no forward pull on the draft-rope K, the movable jaw Z will be caused by the weight of the load to forcibly engage the rope and block it against movement. A forward pull on the draft-rope, as when raising a` sling of hay, will, through the pulley J, depress the levers G, G, thereby raising their short arms G1, G1, to engage and lift the lugs F1, F1 and raise the movable aw d and release the rope. In order to more securely engage the rope, one of the jaws (Z is preferably provided on its concave surface ZK with cross-ribs (ZY. l/Vhen it is desired to release the rope without pulling forward on the draft rope K, as when it is desired to lower the sling, the levers G, Gr are depressed by means of a latch rope N attached to eyes nca formed at the ends of said levers.

lt is apparent that the details of mechanical construction shown herein in describing j one embodiment of my invention may be variously modified without departing from the spirit of the invention and l do not wish to be limited thereto except as pointed out in the appended claims.

l' claim as my invention l. ln a cross draft hay carrier, in combination with the main frame, the draft rope, a pair of opposing jaws, one of which is movable, interposed in the path of the draft rope, an auxiliary frame vertically movable with respect to said main frame, said auxiliary frame directly supporting the load and being rigidly secured to said movable jaw, and means operatively connected to the main frame adapted to be actuated by a forward pull on the draft rope to raise said auxiliary frame.

2. In a cross draft hay carrier, in combination with the main frame, the draft rope and the draft rope pulleys, a fixed jaw secured to the main frame forming one of the supports of said draft rope, a movable jaw adapted to engage and lock the draft rope against said fixed jaw, said movable jaw being actuated by the load, and means automatically operated by a. forward pull on the draft rope to release the movable jaw from its engagement with said draft rope.

3. ln a cross draft hay carrier, in combination with the main frame, the draft rope, a pair of opposing jaws interposed in the path of the draft rope, an auxiliary frame vertically movable wit-h respect to said main frame, said auxiliary frame directly supporting the load, one of said jaws being secured vto the main frame and the other being secured to the auxiliary frame, and means operatively connected to the main frame and actuated by a forward pull. on the draft rope adapted to raise said auxiliary frame to release the grip of the aw secured to said auxiliary frame.
